IMPROVEMENT IN STEAM-PUMPS.

Specification forming part of Letters Patent No. 123,661, dated February13, 1872.

SPECIFICATION FOR IMPROVEMENT IN Poms.

We, LUorEN H. ALLEN and W LLIAM BAB- TON, of Tamaqua, in the county ofSchuylkill and State of Pennsylvania, have invented certain new anduseful Improvements in Pumps; and do hereby declare the following to beafull, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

The nature of our invention consists -in a pump to be used for miningand other purposes; and its object is to throw a continuous stream, andto keep. the water at an uninterrupted flow, so that, when the column ofwater is once started it will continue to move so long as the pump is inmotion.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawing which formsa part of this specification, and in which- Figure 1 is a plan or topview of our improvedpump. Fig. 2is a side view of the same.

AB represents two steam-cylinders arranged in horizontal or otherposition parallel to each other, or in any other position, as desired. 0D E F are four pump-working barrels, arranged, respectively opposite toand in line with each other and the steamcylinder A B. G. H are twodouble plungers connected with steam piston-rods I I, through rods J Jand cross-heads K K, thereby imparting a direct motion fromsteam-pistons to pump-plungers. K K are two cross-heads working throughguides L L L L, with wrist-pins M M on ends of same to connectconnecting-rods n n, they connecting on opposite ends with cranks O O,the cranks set at right angles and fastened to crank-shaft P, wherebythe steam-cylinders assist each other over the dead-point, and also keepthe column of water in constant motion,

one pump-plunger being at the end of the stroke,

the other in the middle of the stroke. The column consequently will bekept continually in motion. (1 are receiving clack-chambers, the waterpassing from the tail-pipe through receiving clack-chambers q and pipesS S to pumpworking barrels. R are discharging clack-chambers, the waterpassing from working-barrels through pipes T T and dischargingclackchambers It to column-pipes; the clackchambers q and It beingsupplied with the necessary valves, as shown, so as to work inconjunction with the pump-plungers G H.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The combination of the cross-heads K K with wrist-pins M M, wherebymotion is secured to cranks O O and shaft B through connecting-rods N N,substantially as set forth.

2. The combination and arrangement of steamcylinders A B, piston-rods lI, rods J J, plungers G H, cross-heads K K, wrist-pins M M, guides L L LL, connecting-rods N N, cranks O O, shaft 1?, clack-chambers q R,receiving and discharge pipes S S and T T, working-barrels O D and E F,all constructed to operate substantially as and for the purposeshereinbefore set forth.

In testimony that We claim the foregoing We have hereunto set our handsthis 18th day of December, A. D. 1871.

L. H. ALLEN.
